This invention pertains'to improvements in presses and more particularly to that type wherein 4the material is subjected t-o the action of a plurality of worms or screws mounted 5 within a fixed shell.

The object of the present invention is to provide special feeding means for the material as it enters the press. Y

In'the treatment of certain materials, such,

1o for instance, as cotton seed or packing house products, which'latter contain` tough membranes or elements, the feeding thereof becomes a troublesome factor. Ordinary spiral feeding` devices cooperating with ahopper or chute to feed the material to the intake end of the screws or worms of the press frequently force too much material onto the feed worm and suchspiral continues to pack the same faster than thefeed'worm can carry it off. Often this packed'material 'builds up in the hopper causing the exible spiral feeder to collapse and the lower end thereof to move away six inches or more from the feed worm. Under such conditions it becomes necessary to stop the press and chisel out the compacted mass before any othermaterial can be fed into the press.

The present structure while employmg a spiral feeder provides a special form of such feeder as will do away with this compacting of the material and allow the press to continue its Operation without the necessity of shutting it down for the purpose above speciiied. In other words I propose to employ an open rigid spiral member or what may be termed a ribbon conveyor in the chute or hopper. By reason of the rigidity of the spiral just mentioned, the end thereof never changes its relation with reference to the 0 feeding worm in the hopper but maintains a positive pushing action on the material close to the feeding worm.

The structure is illustrated in the annexed drawings wherein,

Figure 1 is a vertical sectional elevation of so much of a press, a tempering apparatus, and the spiral feeder forming the basis of the present invention as is necessary to an V understanding of the same,

The press proper may be of any approved type but preferably will Vembody the principle of the press such-as is shown in Letters Patent toAnderson No. 7 31,737 dated J une 23, 1903, wherein there is 4provideda shell or casing denoted generally by 1` andthrough. which extends a shaft2 and'aoquilll 3, the latter being provided with an intake feed worm .3a. Said quill,l as well yas the shaft, will be rotated by any suitable means, not shown, the shaft, as will be. seen, carrying one or more `worms 1 which, acting in conjunctionwith the shell 1 compact the material and, press .the liquids such as oil', grease', water,vetc., therefrom. .E K p' 2 Extendingfupwardlyifrom'the intake end of the press is ah'opper 5 from which extends a; spout 6, ,said spout being in communication with atempering trough 7 through openings yorpassages' and 9.- The latter is controlled .by a ga-te 10 which may be' manipulated through an interconnected shaft 11;,an`d a. hand lever 12. g

vMounted for rotation in the vertically extending' spout4 is a spiral feeding device, which, as above'note'd, comprises a ribbon spiral element 13, theconvolutions of which .stand in separated relation, said spiral being `supported by a centrally disposed shaftA 14 land a series of laterally extending lugs or arms 15'. The shaft preferablystops short of theflower end of the spiral. AIn other words the spiral flightl is extended downwardly as indicated in Figure 1 to a point below the lowermost connecting lug 15 which extends out- "wardly from the lower end ofthe shaft. As will be best seen upon reference/to Figures 1 and 4, the lower face or pushing edge of the ribbon or spiral is preferably formed at anangle of forty-five'fdegrees. Thisreduces thepushing action ofthespiral to such y an extent as to preclude the `necessity o f shutl.ting down the press when acting upon certain materials. Were the lower edge of the'spiral f eo perfectlyfstraight across there wouldbe a` tendency to clog when acting upon certain materials; The bevel, however, cuts ldown the effective pushing action and obviates this troulole.V v -V 'The bevel may extend upwardly toward the inner or outer side of the spiral.`
